With the improvement of comfort, economy and safety requirements, a variety of electronic products on the car are also increasing, and the failure rate of the increasingly complex wiring harness is also increasing. This requires improving the reliability and durability of the harness. Many people are interested in the processing and production of Automotive wiring harness. Here for you to briefly introduce the automotive wiring harness technology and production knowledge.

After the two-dimensional product of automobile wiring harness is drawn out, the production process of wiring harness is inseparable, and the process serves the production. Therefore, the author combines the production and process of automotive wiring harness to analyze.

The first harness production station is an open production line. The accuracy of the open process is directly related to the overall production plan. Once an error occurs, especially if the opening size is very short, it will lead to rework of all stations, which will take time and energy to affect the production efficiency. Therefore, the opening size and size of the line must be determined reasonably according to the requirements of the attached drawings during the preparation for opening.

The second station after opening is the crimping process. Determine the crimping parameters according to the terminal type required by the drawing, and make the crimping operation manual. For special requirements, please specify and train operators in the process documentation. For example, some wires need to pass through the sheath before they are crimped. It needs to be pre assembled, then returned from the pre installation station and crimped. In addition, special crimping tools are used for puncture type crimping. The crimping method has good electrical contact characteristics.

Then there is the pre installation process. First, you should compile the pre installation process operation manual. In order to improve assembly efficiency, complex wiring harness must be equipped with pre installation station. The rationality of the pre installation process directly affects the efficiency of the whole assembly. The craftsman has a high level of skill. If the pre installed parts of the components are too small or the assembly lines are not reasonable, the workload of the total assembly personnel will increase and the speed of the assembly line will slow down.

Therefore, process personnel should always stay on site to summarize. The last step is the final assembly process. It can program according to the assembly board designed by product development department, design tools, equipment, material box size, and add the number of all assembly sheaths and accessories to the material box to improve the assembly efficiency.

In addition, the wiring harness process also includes the preparation of material consumption quota table, man hour measurement, worker training, etc., because the technical content is not high, these are not detailed. In a word, the electronic technology content and quality of automotive wiring harness has gradually become an important index to evaluate vehicle performance. Automobile manufacturers should pay special attention to the selection of wiring harness, and must also understand the process and production of automotive wiring harness.
